In a second embodiment of the invention, an air pump assembly is provided comprising a fan and motor for pumping air, and a switching pipe movable between a first position and a second position, and configured such that air is pumped in a first direction through the switching pipe when the switching pipe is in the first position, and air is pumped in a second direction through the switching pipe when the switching pipe is in the second position. In a preferred embodiment, the air pump assembly further includes a housing having an air intake and an air outlet, and wherein the switching pipe includes a first end and a second end, wherein the switching pipe is arranged such that the first end of the switching pipe communicates with the air outlet when the switching pipe is in the first position, and the first end of the switching pipe communicates with the air intake when the switching pipe is in the second position. In this embodiment, air may be pumped from the air intake to the air outlet and through the switching pipe from the first end to the second end when the switching pipe is in the first position, and air may be pumped from the second end to the first end of the switching pipe and through the air intake to the air outlet when the switching pipe is in the second position.
In a third embodiment of the invention, an inflatable product is provided including an inflatable body, a fan and motor for pumping air, and a switching pipe movable between a first position and a second position, the fan and motor inflating the inflatable body when the switching pipe is in the first position, and deflating the inflatable body when the switching pipe is in the second position. The inflatable body may be inflated via the switching pipe when the switching pipe is in the first position. Furthermore, the inflatable body may be deflated via the switching pipe when the switching pipe is in the second position. In a preferred embodiment, the inflatable product further includes a housing, wherein the housing comprises a first air intake, a first air outlet, and a second air intake, and the fan and motor pump air from the first air intake to the second air intake via the switching pipe when the switching pipe is switched to the first position, and pump air from the second air intake to the first air intake via the switching pipe when the switching pipe is switched to the second position. In this embodiment, the housing further may include a second air outlet. In addition, a switching member may be provided extending from and movable with the switching pipe so as to selectively open and close the second air outlet when the switching pipe is moved between positions.
In a fourth embodiment of the invention, an inflatable product is provided including an inflatable body, a fan and motor for pumping air, a housing having an opening communicating with the inflatable body and allowing air to flow between the housing and the inflatable body during inflation and deflation, and a switching pipe, movable between a first position and a second position, the fan and motor inflating the inflatable body when the switching pipe is in the first position, and deflating the inflatable body when the switching pipe is in the second position. Preferably, a switching member is provided extending from the switching pipe, wherein the switching member is moved with the switching pipe, so as to selectively open and close the opening when the switching pipe is moved between positions.
In a fifth embodiment of the invention, an air pump assembly is provided including a housing having an air intake and a first air outlet, a fan and motor configured to pump air from the air intake to the first air outlet, and a switching pipe having a first end and a second end, the switching pipe movable between a first position and a second position, the switching pipe arranged such that the first end of the switching pipe communicates with the first air outlet when the switching pipe is in the first position, and the first end of the switching pipe communicates with the air intake when the switching pipe is in the second position. On activation of the fan, air is pumped from the air intake to the first air outlet and through the switching pipe from the first end to the second end when the switching pipe is in a first position, and air is pumped from the second end to the first end of the switching pipe and through the air intake to the first air outlet when the switching pipe is in the second position. The fan and motor are preferably mounted in the housing. The housing may include a second air outlet. In this embodiment, a switching member movable with the switching pipe may be provided, the switching member opening the second air outlet when the switching pipe is in the first position. The switching member may also close the second air outlet when the switching pipe is in the second position
The present invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:

During inflation, the air pump 12 pumps air into the inflatable product. Air flows through the vent 131 of the holding element 13, the air intake 121 and air outlet 122 of the air pump 12, and the hole 112 on the bottom of the seat 11. Air then flows into the inflatable product via the hole 112 on the bottom of the seat 112.
During deflation, the air pump 12 is rotated in direction X until the rib 123 rests on the seat 11 at another side. As shown in
Referring to
During inflation, the switch 21 is rotated to “INFLATE”. The air intake 221 is switched to connect the side pipe 236, while the side pipe 237 is closed by the housing 225 of the air pump 22. The air pump 22 pumps air into the inflatable product in accordance with a path as indicated by the arrows. In detail, air flows through the vent 239, main pipe 238, side pipe 236 and air intake 221, and out from the air outlet 222.
When inflation is finished, the user rotates the switch 21 to “STOP”. The air pump 22 stops. Also, the air intake 221 and air outlet 222 are closed by the housing 225 of the air pump 22.
During deflation, the switch 21 is rotated to “DEFLATE”. As shown in
Referring to
Referring to
Referring to
To inflate the back support 42, the user turns on the motor switch 433 to activate the fan and motor 435. In addition, the user turns on the valve switch 431 by twisting the cap 4311. The cam element 4312 follows the cap 4311′s rotation as shown in
If the user further turns on the valve switch 431′, then the mattress pad 41 is inflated.

During inflation, the switch 85, for example, is rotated to “INFLATE”. The valve 83 connected to the switch 85 is opened. Meanwhile, the ear 851 of the switch 85 pushes against the slider 87 so that the pair of electrodes 824, 824′ physically contact each other. Thus, the fan and motor 82 is activated to pump air from the top vent 811 to the bottom vent 812. When the switch 85 is rotated to “DEFLATE”, the valve 83 is opened. The ear 852 of the switch 85 pushes against the lever 871 so that the pair of electrodes 825, 825′ contact each other and the pair of electrodes 824, 824′ separate. Then, the fan and motor 82 operates in reverse to pump air from the bottom vent 812 to the top vent 811. Similarly, air is pumped from the top vent 811 to the bottom vent 813 when the switch 86 is rotated to “INFLATE”. On the other hand, air is pumped from the bottom vent 813 to the top vent 811 when the switch 86 is rotated to “DEFLATE”.
Referring to
On the top and bottom of the ring switch 99 are provided a plurality of recesses. Referring to
To stop the inflating operation, the user rotates the ring switch 99 to the position shown in
To deflate the umbrella, the user rotates the ring switch 99 to the position shown in
While the invention has been described by way of example and in terms of the preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
